“The UK govt passed the Enterprise and Regulatory Reform Act which effectively makes so-called ‘orphaned’ content posted on social media sites public domain. Corporations now only need to have made a “diligent search” to find the owner of the content before use. From the article: ‘The Act contains changes to UK copyright law which permit the commercial exploitation of images where information identifying the owner is missing, so-called “orphan works”, by placing the work into what’s known as “extended collective licensing” schemes. Since most digital images on the internet today are orphans – the metadata is missing or has been stripped by a large organization – millions of photographs and illustrations are swept into such schemes.’”
